Developing Java Applications with Spring and Spring Boot

How to do it...

1. Spring Boot gets us going by creating a placeholder test file, BookPubApplicationTests.java, in the src/test/java/com/example/bookpub directory at the root of our project with the following content:

@RunWith(SpringRunner.class) 
@SpringApplicationConfiguration(classes =    BookPubApplication.class) 
public class BookPubApplicationTests { 
  @Test 
  public void contextLoads() { 
  } 
} 

2. In build.gradle, we also get a test dependency on spring-boot-starter-test, as follows:

testCompile("org.springframework.boot:spring-boot-starter-test") 

3. We will go ahead and extend the basic template test to contain the following code:

import static org.hamcrest.Matchers.containsString;import static org.junit.Assert.assertEquals;import static org.junit.Assert.assertNotNull; ...
